Ready-to-play AC drive for HVAC
Smaller carbon footprint through improved energy efficiency
Every so often a product comes along that surpasses everyone's expectations. The ABB standard drive for HVAC is such a product. As the first AC drive dedicated to the HVAC sector, over 300,000 have now been reliably installed in every continent of the world. And with no product failures or delivery issues, the ABB standard drive for HVAC has become recognized as a world beater, winning awards in Italy and the USA for its outstanding engineering.
One of the biggest benefits of using ABB standard drives for HVAC applications is the energy saving opportunity over other control methods that are used in combination with motors running at fixed speed. Rather than have an electric motor running continuously at full speed, an AC drive allows the user to variably control the motor speed, depending on the demand.
Maybe it is the simple user interface? Designed with the simplicity and intuitiveness of a mobile phone. Start-up of the drive could not be easier. Or it could be the inbuilt macros, as standard, for the most common applications. Selecting the application takes only seconds. The drive is programmed with several HVAC applications, including supply and return fans, cooling tower fans, booster pumps and condensers. The intelligence within the HVAC control panel means that the user is given direct and understandable instructions in clear text at all times. Harmonics and RFI emissions are major concerns within many HVAC installations. The ABB standard drive for HVAC fulfils demanding requirements for electromagnetic compatibility. A swinging choke cuts harmonics emissions by up to 25 percent.
In HVAC applications, the most of which are pumps and fans, AC drives can cut energy bills typically from 20 to 50 percent, although higher savings are possible. As such ABB is a world leader in assessing the energy saving potential within the HVAC sector. ABB offers energy audits, coupled with a series of energy saving tools and
calculators inbuilt in drives. Energy audits can rapidly determine just where and how much energy can be saved. Power savings of up to 50 percent can be reached by reducing the motor speed by just 20 percent. In addition, ABB standard drives for HVAC offer a return on investment usually within months on the basis of energy savings alone. For over 30 years, ABB has delivered millions of AC drives worldwide. In 2008 the installed base contributed to some 170 TWh (170 000 000 000 kWh) reduction in electricity consumption. Had this consumption been generated with fossil fuel powered electricity plants, then some 140 million tonnes of CO2 would have been produced. This is equivalent to the annual CO2 emissions of over 35 million cars.
A clean standard against dirty electricity - IEC/EN 61000-3-12 The ABB standard drive for HVAC fulfils IEC/EN 61000-3-12 and carries manufacturer’s written statement of compliance. This means security and simplicity for specifying engineers and facility managers.
Harmonic currents are forms of pollution on the electrical network. The harmonics can cause several undesired effects - flickering lights, failing computers and overheating of electrical equipment.
The new European standard sets strict limits for harmonic currents produced by products connected to the electrical network.
Ambient temperature up to 50 °C in 24/7/365! 4/7 Ambient temperatures affect the output performance of each drive. The hotter it is outside - or inside the cabinet in which the drive is installed - the less current the drive can deliver. This means that the designer has to select the drive according to the peak temperature.
Benefits of the ABB standard drive for HVAC: • Output current values available in simple format at different ambient temperatures • Identical output current values for both IP21 and IP54 units
